Cooling water system includes disjunctor cooling tower, cooling water pump, cooling water pipeline and corresponding instrument valve accessory, cold
But water system uses a disjunctor cooling tower, cooling water pump to be arranged on the outlet pipeline of disjunctor cooling tower.
The draught fan group being made of multiple wind turbines on the disjunctor cooling tower, blower motor use frequency control；For even
The water charging system of body cooling tower is mainly made of pressure sensor, solenoid valve and PLC controller, and solenoid valve is mounted on water supply pipe
On the road, the pressure of pressure sensor detection disjunctor cooling tower water water in basin, delivers a signal to PLC controller, such as detects pressure value
When equal to setting supplementing water pressure value, PLC controller controls the solenoid valve on water supply pipe and opens, and carries out moisturizing, when detection pressure value
When stopping the pressure value of moisturizing equal to setting, PLC controllers control solenoid valve and close, and stop moisturizing.
Control system of standing includes center switch board, PLC controller, frequency converter, cable, upper unit configuration software and corresponding
Electric control element.
The chilled water pump, cooling water pump, technique water pump are all made of frequency control its motor speed.
The disjunctor blower fan of cooling tower also uses its motor speed of frequency control.
Instrument on the pipeline, wherein replacing previous metal type thermometer using temperature transmitter and pressure sensor
And pressure gauge.
Above several big system cooperatings realize that one-part form stabilization produces 2 DEG C of ice water.
The beneficial effects of the invention are as follows：
1, one-part form may be implemented and produce 2 DEG C of ice water；
2, evaporator is changed using horizontal plate, the coefficient of heat transfer that plate changes is high so that the evaporating temperature of freon improves, to make
The refrigerating efficiency of cooling system is improved；
3, it solves compressor problem of oil return, improves the reliability at ice water station.
4, the design of raw water tank and ice water tank, can play accumulation of energy and night produces the function of ice water, saved operation at
This；
5, cooling water pump, chilled water pump, technique water pump use frequency control, are turned by frequency converter frequency control pump motor
Speed makes each water route realize that constant pressure frequency conversion conveying, disjunctor blower fan of cooling tower motor also use frequency control, realizes and press cooling water heat extraction
Big minor adjustment rotating speed is measured, the electrical equipment operation at entire ice water station is more energy saving, while also preventing power frequency motor frequent start-stop
Damage to equipment.

Specific implementation mode：
After raw water delivers into coolant refrigeration system (1) cooling by chilled water pump (4), in storage to ice water tank (3),
Production line is transported to by technique water pump (5) again.
After cooling water delivers into coolant refrigeration system (1) heat exchange heating by cooling water pump (8), into disjunctor cooling tower
(9) heat extraction cools down in.
It is each in control system integration control coolant refrigeration system (1), chilled water system, cooling water system, the technique water system of standing
The linkage work of equipment.
Operation is opened at ice water station, and the disjunctor cooling tower (9) and cooling water pump (8) being first turned in cooling water system make cold
But water cycle is got up, then opens the chilled water pump (4) in chilled water system, opens ice water pot valve (7), is allowed in ice water tank (3)
Water cycle is got up, and is then then turned on the compressor (11) of coolant refrigeration system (1), is started to produce 2 DEG C of ice water.
For raw water tank (2) and ice water tank (3), when coolant refrigeration system (1) is just opened, water temperature in ice water tank (3) compared with
2 DEG C of water temperature is also not achieved in height, opens the ice water pot valve (7) on water pot communicating pipe, opens chilled water pump (4) and extracts ice water tank
(3) water in enters back into coolant refrigeration system (1), circulation temperature lowering, so that the water temperature in ice water tank (3) is dropped to 2 DEG C, at this moment
The raw water pot valve (6) being then turned on communicating pipe closes ice water pot valve (7), and chilled water pump (4) is made to extract the original in raw water tank (2)
Water 2 DEG C of ice water of progress are produced.
When summer produces 2 DEG C of ice water, for raw water temperature at 28 DEG C or so, 28 DEG C of raw water enters coolant refrigeration system (1)
In, it initially enters horizontal plate and changes progress cooling down in A sections of evaporator (19), the evaporating temperature of this section is designed as 5 DEG C, and raw water is logical
Cross horizontal plate and change evaporator A sections (19) and cool to 14 DEG C, changed in B sections of evaporator (20) subsequently into horizontal plate cool down it is cold
But, the evaporating temperature of second segment is designed as -1 DEG C, and B sections of (20) leaving water temperatures of evaporator and 2 DEG C of ratio are changed by detecting horizontal plate
Come to carry out energy adjustment to compressor (11) compared with value.When leaving water temperature reaches 2 DEG C, the working condition of compressor (11) is to grow
The working condition that phase stablizes.Since the energy adjustment mode of compressor (11) is stepless, and can be steadily in the long term in a certain energy level
Operation, so the ice water for producing 2 DEG C that can stablize.If undesirable by adjusting compressor control of Energy Level leaving water temperature error,
It can also be finely tuned by electric expansion valve (18).
When winter produces 2 DEG C of ice water, raw water temperature is relatively low, when raw water temperature is less than 14 DEG C, closes horizontal plate and changes evaporation
When changing evaporator A sections (19) by horizontal plate temperature does not occur for the solenoid valve (15) on A sections of (19) freon flow paths of device, such raw water
Degree variation changes B sections of evaporator (20) into horizontal plate and starts cooling down, and cooling control and regulation mode produces ice water with summer
Program is the same, ensures that the effluent temperature constancy that horizontal plate changes evaporator B sections (20) is 2 DEG C in this way, without because of supercooled
But it freezes.
